DOORCHECK.

Application filed December 21, 1921. Serial No. 523,831.

To all whom it may concern.

Be it known that I, EMORY GLENN SIMP- SON, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Doorchecks, of which the following is a specification.

This invention relates to door checks and has for its object a door check more especially intended for vehicle doors. Ordinary canvas or leather straps are-used to check an automobile door before all the strain is thrown upon the hinges It is the object of the present invention to provide a metal door check which is very much stronger and more durable than the customary leather or canvas strap used for this purpose. Furthermore, it is easily capable of adjustment, which is not possible with most flexible straps. A further feature of this invention is that it affords a completely concealed check strap.

In the drawings,

Fig. 1 is a fragmentary horizontal section through a door and door post.

. Fig. 2 is a similar, view showing the door swung outwardly.

Fig. 3 is an elevation of the face of the post fixture used in connection with my check.

Fig. 4 is a longitudinal section through the door fixture used in the check and a cross section through the post fixture.

7 Fig. 5 is a section taken on the line 55 of Fig. 4:. I 11 Fig."6 is a section on the line 6-6 of g designatesthe usual door post; 6 the door; and a the concealed hinge of familiar type; When the door opens it swings out in the fashion shown in Fig. 2 due to-the placing of the hinge pivot and the shape of the hinge arm. It is desirable to check the door before the hinge arm strikes the side of the hinge pocket, otherwise the leverage of the door is liable to split the post or to tear the hinges outof the post where an unusual strain is brought upon the door.

To accomplish this purpose I provide an all metal concealed check. This comprises a door fixture and a post fixture. The post fixture comprises an angle plate d which is secured by screws to the face of the post and the inside of the post. On the back of the face plate of this fixture is spot welded a channelled stamped plate 6 which forms a housing or keeper for the hooked end f of the rod 9.

On the door post is secured, by screws, an

angle plate 71. A channel 71 is secured to the back of the inside plate by means of the lugs j which are turned over as shown in Fig. 6. This completes the post fixture. This forms a guide for the nut is which slides back and forth in this channel or housing and which is run onto the threads of the end of the rod 9. The back of the faceplate surrounding the hole through which the rod passes forms an abutment for the nut or stop member. Riveted to the top of this channel is a flat spring m whose ends bow out into the channel and consequently bear against the nut at both ends of its travel and thereby prevent rattling.

It is very easy to disassemble the hooked end f of the. rod from the post fixture. The insert n is secured by screws 0 into a socket in the face of this fixture. By removing this insert which completes the hearing and forms the retainer, the rod can he slid far enough to one side to allow the hook to be removed through the front of the plate. When this rod has been removed the same may be turned in. the nut to lengthen or shorten the checking element as is desired.

It will be seen that with the door fixture sunk in the door and the post/fixture sunk in the door post that the checking element is wholly concealed when the'door is closed.

What I claim is:

1. A door check, having in combination, a post fixture, a door fixture, and a rod provi ed with a non-rotatable nut on one end slidable in one fixture against an abutment and having a swiveling connection removably secured in the other fixture.

2. A door check, having in combination, a door fixture,- a post fixture, a rod having a removable nut on one end non-rotatable but slidable in one fixture against an abutment, a spring bearing against the side of a door fixture, a post fixture, a rod provided with a nut on one end non-rotatable but slidable in one fixture against. an abutment, and a hook on the other end having a swiveling engagement with the other fixture.

4. A door check, having in combination,

\adoor fixture, a post fixture, a rod having a nut on one endslidable in one fixture against an abutment, and a hook on the opposite end, and an insert for removably securing such hooked end in the other fixture.

5. A door check, having in combination, a door fixture, a post fixture, one of which is provided with a channel guide and abutment, a rod provided with a nut on one end slidable in said guide,'and a hook on the opposite end having a swiveling con nection in the other fixture.

6. A door check, having in combination, an angle plate securable to the door post provided with a second plate secured to plate and provided with a channel, a xture for securing to, the, door, and a rod slidable in such fixture and having a hooked the back of the faceplate of the an de end which engages in channehformedas in the post fixture.

7. A doorcheck, having in combination, an angle platesecurable to the door post, a plate secured to the back of the face plate of such angle plate and provided with a 30 stamped-out portion forming a socket, a door fixture, a rod slidable in such -door hooked end of the rod in its socket.

In testimony whereof I aifix my signature,

EMORY GLENN SIMPSON.
